从群体支持系统到创造力支持系统

群体支持系统主要支持在合作问题求解过程中沟通、信息共享乃至群决策等各种群体活动,特别是针对非结构化问题.这其中,如何支持群体产生创意(idea),引导深入的分析和论证是研究群体研讨过程的支持工具的最主要的难点之一.这也导致了有关创造力支持系统的研究.简要回顾了创造力支持系统的研究,介绍了所研究的支持群体互动、智慧迸发的群体研讨环境(GAE),其功能强调了“人机结合,以人为主”的设计理念和对研讨过程理性的探索.最后简要介绍该工具在分析香山科学会议上的应用.     

SOME DEVELOPMENTS IN THE STUDIES OF META—SYNTHESIS SYSTEM APPROACH

In the early 1990s, Professor Qian Xuesen(Tsien HsueShen)and his colleagues proposed theMetasynthesis system approach for solving the open complex giant system problems. The methodemphasizes the synthesis of collected information and knowledge of various kinds of experts, andcombining quantitative methods with qualitative knowledge. Later it is evolved into Hall of Workshopfor Meta-Synthetic Engineering (HWMSE)which emphasizes to make use of breaking advances ininformation technologies. Then continuous endeavors have been taken to put those ideas into practice.With tremendous advances in networking and distributed computing technologies, past difficulties inimplementation are disappearing together with further understandings of HWMSE and fruitful resultsachieved in similar or relevant research fields in recent years in China. In this paper some of thosedevelopment are introduced, together with some parallel research work abroad.     

FLUID-BASED SIMULATION APPROACH FOR HIGH VOLUME CONVEYOR TRANSPORTATION SYSTEMS

High volume conveyor systems in distribution centers have very large footprint and can handlelarge volumes and hold thousands of items.Traditional discrete-event cell-based approach to simulatesuch networks becomes computationally challenging.An alternative approach,in which the traffic isrepresented by segments of fluid flow of different density instead of individual packages,is presentedin this paper to address this challenge.The proposed fluid-based simulation approach is developedusing a Hybrid Petri Nets framework.The underlying model is a combination of an extension of aBatches Petri Nets(BPN)and a Stochastic Petri Nets(SPN).The extensions are in the inclusion ofrandom elements and relaxation of certain structural constraints.Some adaptations are also made to fitthe target system modeling.The approach is presented with an example.

中国节能减排系统动力学模型及政策优化仿真

为考察并比较不同节能减排政策对能源消耗和污染物排放的影响作用,从政府、经济、人口、科技、能源和环境等系统要素出发,构建了节能减排系统动力学模型;并以福建省为例,确定模型参数及主要方程,在各个子系统上分别赋予税收、金融、财政、环保、产业和科技等政策调控因子,动态仿真不同工具的实施效果.研究结果表明:在设定的情景及参数下,政策的调整与实施往往能够促进节能减排,但不能盲目改变政策的实施力度.不同政策其节能减排效果不同,税收、环保和产业政策对节能减排产生的效果最为明显,其中环保政策下环境相对污染度虽降幅不及税收政策,但主要污染物的前端治污效果凸显;而金融、财政和科技政策的节能减排效果较为微弱.     

基于城市金融竞争力评价的我国多层次金融中心体系

为了对我国的多层级金融中心体系进行研究, 论文设计了一套系统的评价方法. 在评价过程中, 首先建立了评价各城市金融竞争力的指标体系, 接着采用熵权法、灰色关联分析法、主成分分析法等对我国21个大中城市的金融竞争力进行了评价, 再运用Kendall协同系数检验法对三种方法评价结果的一致性进行了检验并进行组合评价, 给出了各城市金融竞争力的排名, 最后还运用K-均值聚类分析法将21个城市划分了层级. 根据评价的结果以及区域经济发展的特点和各城市的优势和差异, 对我国多层次金融中心体系格局的构建给出了政策建议.
